| From: | To: |
A Retirement Interest Only (RIO) Mortgage is a type of mortgage available in the UK for retirees where borrowers only pay the interest on the loan each month, with the capital repaid at the end of the term from the sale of the property or other assets.
The calculator uses the simple interest-only formula:
Where:
Explanation: This calculation determines the monthly interest payment only, which remains constant throughout the loan term as the principal balance doesn't decrease.
Details: Accurate calculation of interest-only payments is crucial for retirement planning, ensuring borrowers can afford the monthly payments while preserving their capital for later repayment.
Tips: Enter the principal amount in GBP and the monthly interest rate as a decimal (e.g., 0.00417 for 5% annual rate ÷ 12). Both values must be valid (principal > 0, rate between 0-1).
Q1: What is the difference between interest-only and repayment mortgages?
A: Interest-only mortgages require paying only the interest each month, while repayment mortgages include both interest and principal reduction in each payment.
Q2: How do I convert annual interest rate to monthly?
A: Divide the annual percentage rate by 12 and convert to decimal (e.g., 5% annual = 5/12 = 0.4167% monthly = 0.004167 decimal).
Q3: What happens at the end of a retirement interest-only mortgage?
A: The borrower must repay the original loan amount, typically through property sale, inheritance, or other investments.
Q4: Who qualifies for retirement interest-only mortgages?
A: Typically available to older borrowers (usually 55+) who have sufficient equity in their property and can demonstrate affordability of interest payments.
Q5: Are there risks with interest-only mortgages?
A: The main risk is having a repayment strategy that may not materialize, potentially leading to the loss of the property if the capital cannot be repaid.
